TB/A]? FOR BRAINS AND SEWER/S.

Application filed September 20,1926. Serial no. 136,645.

The object of this invention is to provide a trap adapted to bemanufactured in all sizes, so that it will be suitable for street use,for floor drains, and under practically all conditions in which a largeor small volume of water is to be taken care of, and where a water sealis necessary or desirable for preventing odors and gases from causingannoyance or from producing dangerous conditions.

A further object is to provide, in a device of this character, aplurality of detachable elements for cooperation with an elementpermanently mounted in cement or concrete, or in the bottom of areceptacle for waste water.

With the foregoing and other objects in View, the invention consists inthe novel construction and arrangement of elements described,illustrated and claimed, it being understood that modifications may bemade within the scope of the claims without departing from the spirit ofthe invention.

In the drawings forming part of this application,

Figure 1 is a view of the device in vertical section, the view alsoshowing Walls of cement or concrete between which the containerproviding the water seal and the other elements are mounted.

Figure 2 is a top plan view of the structure of Figure 1.

A container or receptacle 10 is provided with an upper flange 11 andwith an opening 12, the latter being above-the bottom of the receptacle,and determining the level of the liquid therein. It will be assumed thatthe container discharges thru opening 12 to any suitable duct or sewer.

A dished element 14 includes an upper flange 15 adapted to rest on theshoulder 16 formed in the cement or concrete work, so that the uppersurface of flange 15 will be flush with the paving or other surfaceportion 17. Element 14 is provided with an upwardly extending flange 18having an inclined surface as shown, and with a flange 19 providing ashoulder at 20 on which the flange 11 of the receptacle 10 is adapted torest. Contact is made by gravity alone, for the reason that it isdesired to have the parts detachable for cleaning, without the necessityof taking the time required for the disengagement of securing devices.

The inner element of the device includes the upwardly and outwardlyflared portion 24 adapted to receive at its upper edge the beveled edges25 of a plate or grating- 26. Element 24 further includes the downwardlyextendmg flange 27 adapted for reception within the channel formed at 28in the element 14 before mentioned. I

A flat surface 30 appears in Figure 1, and a funnel shaped element 31extends downwardly from the inner edge of portion 30. this element 31projecting to a point below the liquid level as defined-by the loweredge of opening 12, constituting the discharge opening.

It will be observed that the shoulder formed at 20, and the flange 11resting thereon, underlie the portion 30. and that the joint, or loosejoint, produced between the elements 20 and 11 is thoroughly protectedby the continuous surface formed by the flared portion 24, thehorizontal portion 30 and the inner wall 31 of the funnel. Particularemphasis is placed upon the fact that all parts are promptly detachablefor cleaning purposes, that the separate elements may be formed of anysuitable material depending upon the particular use to which the trap isto be placed, that the liquid flows thru an inner element the walls ofwhich are continuous to the point of discharge, and that the receptacle10 is suspended on an outer element such as the dished member 14, thejointat 11 being out of the path of movement of the liquid.

Having described the invention what is claimed is:

'1. In a device'of the class described, a container having an opening inthe side wall thereof, a funnel-shaped device extending into thecontainer below the opening thereof, providing a water seal, an upwardlyand outwardly flared element projecting from the upper edge of thefunnel and offset from the wall of the funnel to provide. an inwardlyextending portion, and a dished member receiving the flared element andhaving a flange for engaging the container at a point below the inwardlyextending portion of the flared element.

2. In a device of the class described, a container having an opening inthe side wall thereof, a dished member having a lower inwardly extendingflange, a second flange con nected with that first named, a containersuspended from one of the flanges, and an inner detachable elementincluding an upper flared portion, a lower funnel portion extending intothe container below the opening in the wall thereof and an intermediateportion engaging the other flange and projecting in wardly toward theupper portion of the container.

3. In a device of the class described, a container having an opening inthe side wall thereof, a dished member having-a lower inwardly extendingflange, a second flange connected with that first named, a containersuspended from one of the flanges, and an inner detachable elementincluding an upper flared portion, a lower funnel portion extending intothe container below the opening "in the wall thereof and an intermediateportion engaging the other flange and projecting inwardly toward theupper portion of the container, said dished member having an upperoutwardly extending supporting flange, and a grating supported withinthe upper portion of the inner detachable member.

111 testimony whereof I affix my signature.
